ATTACHMENT FOR .ANVILS.

T 0 all whom it may concern:

Be it known that I, ABEY H. DE HAAs, a citizen of the United States,residing at Goodnight, in the county of Logan and State of Oklahoma,have invented certain new and useful Improvements in Attachments forAnvils, of which the following is a specification.

My invention relates to an attachment for anvils, my object being toprovide a simple and strong device that will hold cutting and punchingtools and the like in an operative position whereby to do away with thenecessity of a helper in cutting and punching operations and the like.

lVith this in View, my invention resides in the features to behereinafter set forth with respect to the accompanying drawing, inwhich- Figure 1 is a side elevation of an anvil provided with myimproved attachment. Fig. 2 is a plan view of my attachment removed.Fig. 3 is a vertical transverse section therethrough on line 33 of Fig.1, and, Fig. 4 is an elevation of several sets of tools among thosewhich may be used with my attachment.

Referring to these figures, my attachment comprises upper and lowerelongated U- shaped frames 6 and 7 connected at their rear open ends bya vertical bar 8, the lower end of which is securely riveted to the endof the lower frame 7 and the upper portion of which has a verticalseries of openings 9 any one of which may constitute the fulcrum forvertical swinging movement of upper frame 6, by a pin 10 throughopenings in the rear end of said frame. The upper frame 6, besides beingadapted to swing vertically, is thus adjustable to and from the lowerframe 7 at its point of pivot. The two frames 6 and 7 may also haverearward projections 11, connected by a spring 12 whereby tocounterbalance the frame 6, which is prevented from sidewise movementand guided in its vertical swinging movement, by a vertical bar 13upstanding therethrough at a central point, from the lower frame 7through which the lower end of said bar 13 is rigidly riveted. The lowerframe 7 is attachable upon the anvil A, as shown in Fig. 1, by a taperpin 14 which projects Specification of Letters Patent.

downwardly through the usual anvil opening, and has an upper opening bywhich it is locked through openings in said frame just forwardly of bar13, with a transverse pin 15, and has a lower opening by which it islocked through the said anvil opening with a transverse pin 16 beneaththe heel of the anvil.

The forward ends of the frames 6 and 7 are squared to receive thesquared shanks of opposing tools, for instance hot cutters 17 swages 18,fullers 19, round punches 20 and square punches 21, as shown in Fig. 4c,the said shanks of said tools having side recesses 22 to receivetransverse pins 23 engageable through openings in said frames adjacenttheir said squared ends, to maintain said tools in position. Of coursethe shanks of the tools to go into the upper frame are somewhat longerthan the others, so as to provide for striking heads.

. The operation of my attachment that is the raising of upper frame 6 toinsert the work between the tools, and the vertical adjustment of saidframe to accommodate different sizes of work will, it is thought, bereadily understood.

I claim:

1. An attachment consisting of a pair of superposed frames, meanscarried by the lower frame to attach the same upon a support, a barupstanding from one end of the lower frame, relatively engaging meansconnecting the rear end of the upper frame to said bar for adjustmenttoward and from the lower frame, and forming a fulcrum for verticalmovement of the former, means to guide the upper frame in its swingingmovement, and tools and means to support the same in opposing relationin the opposite ends of said frames.

2. An attachment of the character described comprising upper and lowerelongated U-shaped frames, a pin locked within the lower frame anddepending therefrom, a bar rigidly secured to, and upstanding from oneend of said lower frame and having a series of apertures, a memberextending through the adjacent end of the upper frame for engagementthrough a selected opening of said series and forming a fulcrum for saidupper bar, said frames having their op- In testimony whereof I afiix' mysignature in presence of two Witnesses.
